LOADING MACHINE.

Application filed December 11, 1922. Serial No. 606,235.

This invention relates to improvements in loading machines, and isespecially directed to loading machines adapted for employment inunderground coal mines for the purpose o'l' mechanically transferringcoal, after the latter has been broken down in a loose, semisolid orshattered state from the original solid vein or bed, into mine or pitcars for transportation out of the mine.

The primary object of the invention resides in the provision of aloading machine of the above character constructed to provide mechanicalmeans for economically and rapidly loading coal into suitable carrierswith but a minimum of manual operations.

Another object of the invention resides in the provision of a machinewhich will constitute an improvement upon the structure of the machinedisclosed in my co-pending application, Serial No. 439,092, filedJanuary 22, 1921, by providing an improved driving arrangement for theconveyer units disclosed in said application.

The principles of the invention are found in the provision of a loadingmachine which is formed to comprise progressively arranged gathering anddelivering conveyers, the gathering conveyer being formed to include aconveyor belt having its going and return sections disposed at the sameelevation and mounted or movement upon an elongated inclined frame,which has its rear or elevated end mounted upon a supporting structurewhich includes vertical and horizontal axes, located to permit thegathering convoyer to swing bodily in both horizontal and verticalplanes, so that the trout end thereot may be maintained in engagementwith the material to be gathered and loaded, the delivering conveyerbeing formed to comprise a frame which includes a hopper, situated atall times beneath the discharge end of the gathering conveyer, andwherein the said delivering conveyer further includes a conveying beltwhich has its going and return runs located in ditterent planes, theupper run of the delivering conveyor belt being arranged to pass overand out of the bottom of the hopper to remove materials from said hopperand deliver the same into suitable independent carriers placed beneaththe rear elevated end of the loading or delivering conveyer. Thisarrangement of conveyors has been disclosed and claimed in my lie-issuePatent No. 15,339, issued April 18, 1922.

A further object of the invention rests in providing a single motorwhich is employed for the purpose of driving the conveying belts of thegathering and delivering conveyers, to eli'ect the propulsion of themachine and to operate the mechanism for positively effecting bodilylateral swinging movement on the part of the gathering conveyer in lieuof employing a plurality of motors for etlecting these differentoperations.

A still :turther object of the invention resides in forming the drivingmechanism to include a reversible motor driving directly to the belt ofthe gathering conveyor, whereby upon the reversal of the direction ofrotation of the motor, the direction of movement of the gatheringconveyor belt may be controlled at will, there being a drive connectionfrom said motor to the belt of the delivering conveyor, which includesan automatic reversing mechanism arranged and constructed to operate thebelt of the delivering conveyer in but one direction, i. e. the draftdirection, irresp votive of the direction of rotation of the motor, thesaid motor being further connected with the supporting base of themachine upon which the conveyors are mounted, in order that motion maybe imparted to the machine to move the same from place to place,independently of or conjointly with the operation 01 said conveyorbelts.

A still further object of the invention rests in the provision of animproved mechanism tor ell'ecting the side swinging of the gatheringconveyor. in which said side swinging mechanism is driven directly fromthe belt of the gathering conveyer, wherein mechanism is included forcontrolling the direction of movement of said side swinging mechanismindependently of the direction of movement of the gathering conveyorbelt.

With these and other objects in view, as will appear as the descriptionproceeds, the invention consists in the novel features of construction,combinations of elements and arrangements of parts, hereinafter fullydescribed and pointed out in the appended claims.

Ihave found it advisahle to o oi the truck, and it Wi all the rollers 18are disposed so that the same will engage with the under surface of thebed plate, a feature which prevents loose coal or other material frominterfering with the action of the rollers. For example, if the rollers18 are carried so as to depend from the bed plate 16 and engage with theend frame, accumulated coal deposit would seriously interfere with theiroperation. how-ever, by the arrangen'ient shown, this dilliculty isobviated and a structure provided by means of which the bed plate andthe mechanism supported thereon may be conveniently oscillated in ahorizontal plane.

To effect this oscillation of the bed plate 16, I provide the end frame8 with an arcuate rack 19 and the bed plate with a sprocket 20 disposedin engagement with said rack and mounted upon a suitably journalcd shaft21. This shaft has its upper end equipped with a worm gear 22 arrangedto mesh with a worm 28 mounted upon the intermediate portion of a1 shaft2th., which is journaled in connection with the bed plate and has theends thereof equipped with hand wheels by means of which the shaft 2%may be manually rotated. Obviously, pen the rotation of the shaft 2%.motion will be in'iparted to the sprocket 20 to cause the shifting ofthe bedpiate to any desired extent, and by reason of the worm gearing anautomatic lock is provided for maintaining the bed plate in any of itsadjusted positions.

Disposed upon the forward end of the bed plate 16 is a pair of bearings26 with which are connected studs 27 arranged to project horizontallyover the bed plate. l rumiioncd upon these studs is the lower end of thesupporting structure D of the gathering: conveyer, which structure inthis instance coniprises a. yoke shaped casting 28 having); the lowerbifurcated end the eof suitable mounted upon the studs 27 to rock in avvertical plane with the axis of said studs as a center. Arranged to passthrough the hub portion of the. casting is a drive shaft 30 for thegatherllll' conveyor, and positioned around this shaft and mounted uponthe upper end of the hub is the pivot flange casting 31 of the gatheringconveyor. The enlarged flangz'c 32 of this casting is riveted orotherwise sccured to the bottom plate 33 of the frame 2, and the hub 34of the casting; 31 has its lower end mounted upon a metallic wearreceiving washer 35, which is positioned around the shaft 30 anddisposed upon the upper end of the hub 29. ft will be seen that by thisconstruction, the gathering convcyer frame will be so supported that thesame may swing about the vertical axis provided by the shaft 30, inorder that the forward or nose end of the frame may oscillatehorizontally across a mine floor in advance of the truck C, andfurthermore, said frame will be permitted to follow the contour of themine floor by means of the horizontal pivot provided by the studs 27 andassociated parts. A compound pivotal structure is therefore provided forthe ga hering convcycr. However, when the gathering conveyor frame isswung to assume extreme angular positions with respect to the longitudiual center line of the machine, or positions in which the studs 27 arenot completely effective in permitting of vertical oscillation of theframe 2, the springs 14; in the journal boxes of the truck permit themachine to oscillate bodily a sutiicient extent to avoid breakage orstrains of parts connected with the gathering conveyor.

Mounted upon the upper end of the shaft on is a disk clutch 236. thedriven member of which being; formed to include a sprocket 37, whichconstitutes the driving sprocket of the endless conveying belt 38 of thegathering conveyor. This belt, in the present instance. is of the linkor chain variety, strongly constructed and flexible in vertical andhorizontal planes to readily follow the contour of the bottom plate ofthe frame 2, the going: and return runs of said belt being disposed atsimilar elevations, or in other words. the belt is of the type commonlyrefcrrcd to as the single plauetypc, and the specific constructionthereof has been disclosed in Figure 9, although this belt is not.claimed per se in this application. Angle irons 39 are mounted upon thebottom plate 33 and are formed to comprise guides 40, which extendlongitudinally of the frame 2 and are transversely spaced to enclose theopposite runs of the belt and protect the links thereof from theclogging action of loose coal. The belt is also constructed to includeas a unitary portion thereof a plurality of appropriately spaced flightanchors ell, to which are bolted laterally and horizontally extendin srflights 42, disposed to travel alternately in a pair of runways 43provided in the frame 2 between the guides and the sides el-l of theframe. At the ill) forward or lower end of the frame. there is provideda longitudinally adjustable nose sprocket elf), around which the belt 38trained. the said sprocket -15 being suitably enclosed by means of aIClIlOVHl'dQ housing 46, beyuind the periphery of which project theflights 42, the said flights also being of sufficient length to projectbeyond the beveled periphery of the nose end of the frame 2. It will besa n by this constructitm that when the clutch 36 is thrown in. motionwill be imparted to the drive sprocket 37, which imparts movement to thegathering convcyer belt as a whole, causing the spaced flights 42 topass lougitiuliually through the rumvays a3, and that these runways arealternately available to pass coal thcrethrough in a draft direction inaccordance with the direction of rotation of tlie sprocket 37. It willbe observed that the flights as they pass around the clined at its frontend to constitute the bottom of the hopper 65, the extreme lower end ofsaid bottom being appropriately spaced from the elevated end of thebottom plate 33 to allow large lumps of coal to be deposited within saidhopper so as to avoid interference with the revolving horizontallytraveling flights of the gz'ithering convcyer. In the event, however,that the hopper should become filled with coal to such an extent as tointerfere with the movement of the flights, relief will be affordedautomatically or manually by the clutch 36, however, for ordinarypurposes, the hopper is of sullicient depth to preclude suchinterference. A conveyer belt 71 is provided in the frame I and is of atype wherein the going and return sections are in different planes. Inthis instance, the belt '71 includes a pair of longitudinally extendingtransversely spaced endless chains 72 of the link variety, which areadapted to pass over sprockets 73 at the forward end of the hopper andover similar sprockets Tet at the extreme rear end of the frame F. Thesprockets 73 are loosely mounted for rotation upon the transverselyextending shaft 7 5 which has its ends mounted within the bearings 26 onthe bed plate 16, whereas the sprockets H. are fixed upon a drive shaft76 disposed at the extreme rear end of the frame F. The chains 72 areunited by longitudinally spaced transversely extending flights 77, whichtravel over the bottom of the hopper and are adapted to move coal in adraft direction through the loading conveyer frame F. These flights areof sufficient height to securely engage with the coal and move the sameup the forward inclined portion of the bottom 70 and to finallydischarge the coal from the rear elevated end of the fran'ie F into anunderlying mine car, designated by the letter G. The drive shaft 76 isplaced at the rear of the frame instead of at the forward end thereof inorder that the chain may pull the coal instead of pushing it. Thisconstruction makes for better chain operation and engagement between therollers of the chain and the sprockets.

To drive the delivering conveyor, the lower end of the shaft 30 isformed with a beveled gear 78, meshing with a similar gear 79 providedupon a transversely extending shaft 80 journaled in the bearings 26beneath the shaft 75. The shaft 80 is provided with a feathered clutch81, disposed for engagement with a clutch hub 82 provided upon asprocket 83 loosely mounted on the shaft 80. For convenience inillustration, I have disclosed a jaw type of clutch, but it will beunderstood that any other suitable form of clutch may be employed iffound desirable. The sprocket 83 has trained thereover a chain 84:,which leads to the double sprocket 85, loosely mounted upon one end ofthe shaft 75, and from the sprocket 85 an endless chain 86 leads back tothe automatically reversing mechanism 87. This mechanism is disclosed inmy aforesaid application and is therefore not claimed per se in thisapplication. However, to effect a complete disclosure, the same has beenillustrated herein and described, the office thereof being to provide adrive for the delivering conveyor which will operate the latter in butone direction only irrespective of the direction of movement of thegathering conveyer. This condition is necessitated when it is understoodthat the gathering conveyor must be reversed when in operation so as togather material when moved in one direction or the other about itsvertical axis, but it is essential that the delivering conveyor shallmore in but one direction, to-wit, a draft direction, and since bothconveyers are driven from a single reversible motor, I find thereversing mechanisn'i desirable.

It is of course possible that this mechanism could be operated by hand,but by rendering the same automatic, a detail in the operation of themachine is removed from the mind of the operator or runner.

The reversing mechanism has been disclosed in Figures 12 and 13 and asshown, includes a sleeve 88 loosely mounted for rotation upon a fixedstud shaft 89. The sleeve is provided with a sprocket 90 over which thechain 86 trained. Fixed upon the sleeve and rotatable in unison with thesprocket 90 a second sprocket 91 and a gear 92, the sprocket 91 havingtrained thereover a short chain section 93, which leads to the sprocketO l loosely mounted for rotation upon a stud shaft 95. Similarly, thegear 92 is in mesh with a. gear 96 loosely mounted upon the shaft 95.The sprocket 9 t and the gear 96 are formed with clutch hubs 97 havingreverscly disposed clutch teeth 98 formed therein, which teeth areadapted for alternate engagement with similarly formed teeth 99 providedupon a hub 100 of a floating sprocket 101. By this construction, it willbe seen that when the primary sprocket 90 is revolving in a clock-wisedirection, motion will be imparted to both the sprocket 94 and the gear96, but the latter elements will rotate in opposite directions, andsince the sprocket 9-1 will be movingin a clock-wise direction, theangularity of the teeth upon the hub thereof will cause the floatingsprocket 101 to be shifted upon the shaft so that the said floatingsprocket will be clutched with the teeth of the gear 96. Conversely,when the sprocket 90 is driven in a counter-clock-wise direction, thefloating sprocket will be automati ally shifted into engagement with theteeth of the sprocket 94C, and therefore the direction of rotation ofthe floating sprocket will be maintained constant, irrespective of thereversal of movement of the main operating motor E. A relief sprin 102may be provided to permit of slight relative sepa tion of the sprocket94 and. the 90 in the outer tips of the clutch teeth pro to upon the hubof the floating sprocket meet with the outer tips of the teeth providedor the hubs of the sprocket 94 one the gear 96. Over the floatingsprocket 101 an endiees chain 103 is trained, the said chain being alsopassed around a sprocket 10% provided upon the drive shaft 70 of the(tieiiverihg eyer. g

Worm gem 11' to rot: 110 t" vided with a second sprocket s pessee aheavy rolier eheirr 0 eerr it is obvious that when the wheel elementrotates, the gathering conveyer frame may be positively drawn from oneside of the room to the other, swinging about the vertical axis of theshaft 30. The present iuvention includes mechanism whereby the wheelelement is driven from the chain and its direction of rotation reversedindependently of the direction of movement of said belt.

To secure these results, use is made of a sprocket 135, shown in Figures8 and 1). This sprocket is mounted intermediately of the frame 2 uponthe inclined portion thereof and is disposed in parallelism with thebottom plate 83 of the frame between the angles 39. The teeth of thesprocket are so cut or formed that the same w ll project through a slot136, provided in at least one of the angles 39, in order that said teethmay mesh or engage with the links provided in the belt 38. Thus, uponthe movement of the gathering ciiinveyer. motion will be imparted to thesprocket.

Surrounding the sprocket a bearing structure 137, which receives forrotation a shaft 138, fixed to rotate with said sprocket and forming theaxis thereof. Also rotatable with the shaft 138 a beveled gear 139arranged to mesh with "and disposed above a pinion 110, this arrangementbeing found to be preferable in order to prevent loose coal frominterfering with the toothed action of the gears 139 and letO.

Mounted for rotation within the bearing structure 137 is alongitudinally extcmling shaft 141, upon one end of which is mounted thepinion 140, the other end of said sha t't having keyed or fixed theretothe outer sec tion 1&2 of a cone clutch. The driven or inner section 143of said clutch is feathered upon a longitudinally extending sha't't111i, journaled for rotation in alignment with the sha it 141 and formedto rotate with said shaft when the clutch is thrown in, which ma v beaccomplished by the manual controls 11.3.

Upon the shaft 141- are loosely mounted gears M6 and 151 of a reversingmechanism, said gears meshing with a gear 148 lixed on a suitably'supported stud shaft 150. 119 designates a shi't'table clutch sleeveadapted to couple the shaft fill with either gear 1-16 or gear 151, thelatter gear being tized to a sleeve 152. By throwing the clutch section113 out of engagement with the driving section 1e12, it will beunderstood that the reversing gear mechanism may be set so that when theclutch is again thrown in, the direction of rotation of the sleeve maybe governed at will, and consequently the direction of rotation of thewheel element 1331 accordingly controlled in a manner independent of themovement of the gathering conveyor belt.

The lower end of the sleeve 152 is 0011- nected with a universal joint153 with a horizontally extending shaft 154: which is emploved toactuate a sleeve locking eccentric drive mechanism for the wheel element131. As shown in Figures 10 and 11, particularly, this eccentric drivemechanism includes a spur gear 155 arranged for rotation within a lixedcasing 156. the gear 155 being mounted upon the inner end of the shaft15-1. Arranged to mesh with the g rar 155 is a pair of spur gears 15?,which are carried by a pair of eccentric shafts 158, joiiirnaled forrotation in the ends of the casing 156. The said casing is provided witha central partition 150, which divides the easing into a gear chamber160 and an eccentric chamber 161. Fixed upon the shafts 158 within thechamber 161 are eccentrics 162, which are disposed within openings 163provided in a plurality of rack plates 161. Each of these plates isprovided with a centrally disposed opening having rack teeth 165 alongthe upper and lower surfaces thereof, said rack teeth being arrangedrectilinearly and adapted to be alternately engaged with a pinion 166fixed to a shaft 1167 upon which the wheel element is mounted. By thisconstruction, which is employed in most chain hoist constructions,rotation of the eccentrics 162 will cause the plates 16st to move insubstantially elliptical orbits in which the rack teeth thereof will beintermittently engaged with the pinion 166, the arrangement of the saidplates, however, being such that certain of the rack teeth will beconstantly in engagement with the pinion 166, a feature which insuresthe locking of the wheel element in any given position of rotation. Thiseccentric drive while pmverful and effective necessarily quite slow, andtherefore, a proper speed is secured by providing an enlarged gear 139and a small pinion 1 10.

In view of the construction described. it will. be manifest that thepresent invention provides a loading machine having essentially a singleprime mover. This construction is desirable in. that it eliminates theemployment of a large number of motors, controllers and resistance,wiring and other apparatus connected therewith, and reduces thepossibility of serious delays resulting from motor troubles in the useof the machine. Itl'otors are constantly at source of trouble in mostmining equipment. because of poorly mounted conductors, improperlybonded rails, improper installation, low voltages, absence of properelectrical and mechanical inspection and other very important causes.The present invention aims to reduce this trouble to a minimum byproviding a single motor which serves to actuate all of the cooperativeunits of the machine. Thus a single motor is provided which operates thegathering conveyor, the loading conveyor, the propelling mechanism andthe side ill) lit)
